clutch options

[redamnavit]

I've been researching what options are available for the CA18DET with regard to clutches and flywheels. This is what I have so far. I'll add to this as I discover more; I haven't finished poking around all the UK and AU boards to see what they're using.

SPEC : We all know this one.

ACT : I haven't verified it, but ACT supposedly makes/made a CA piece.

ATS Has multiplate clutches and accompanying flywheels.

Unless otherwise noted, the japanese brands are found at Taka Kaira. I'll be making a wider search of the japanese offerings but TK was an easy place to start.

Toda : Toda makes a clutch/flywheel/cover.HKS : HKS offers (still?) a flywheel and clutch.http://www.kempower.be/ HKS

MUD - Very reasonably priced metal clutch/flywheel/cover for the CA18. Yes, MUD is the company's real name.

Ogura : Ogura makes a beautiful flywheel/clutch set, at a highly unattainable $919.

OS Giken : OS Giken offers single/multiplate CA18 clutches, pressure plates and uprated clutch slave cylinders. www.greenline.jp Otomoto - an AU supplier.

Cusco : Cusco has a super lightweight (5kg!) flywheel for $388. They also offer a metal puck clutch for $231. Cusco sells two different kinds of clutches though; metal puck and an organic disk. I'm looking into whether they have the disk in a CA18 application.

Jun : Jun makes a lightweight and super lightweight flywheel for the CA. Sorry, I forgot to note the prices.

Daikin/Exedy : I believe Daikin made the stock clutch for the CA, and my motorset had an Exedy-branded piece in it. I have inquiries into the US division about what they currently produce for the CA.

Nismo : Nismo does offer an organic clutch, paddle clutch and pressure plate for the CA. Price range is the mid 600s for the clutches. apexperformance.co.uk

Other UK : Norris Designs offers some options for the CA, as does a company called LUK. From what I read and given shipping costs, you'd probably be just as well off going with SPEC if you're in the US.

Centerforce : Centerforce offers a dual friction clutch for the 1987 Pulsar (which I believe fits) for $257.

Unique Autos in Australia offers UAS and ATS clutches and flywheels for the S13/180sx, but they don't note which motor they go with. I'll work on it. The ATS models start at over 2900 AU dollars.

horsepowerinabox Has ceramic puck clutches and pressure plates with 40% and 75% increase over stock. $800 AU.

Some other info :-CA18DET/CA18ET clutch are compatible, at 225mm.

-The RB20 clutch is said to be identical to the CA18DET's clutch. I doubt RB20 clutches will be any easier to come by than CAs but its worth noting.

If anyone can add to this, feel free. If anyone found an odd clutch in their motorset when they received it, please post those as well. It'll give me a direction to search in.

Us RB20 guys noramlly use NA Z32 clutch kits. The TO bearing and pressure plate are SLIGHTLY different thann those of the R32 sets but they mount up and work perfectly, aslong as you don't mix and match R32 and Z32 stuff. Just a little FYI for the 4 cylinder RB community.

SeVa-S13, do you have an old clutch sitting around that you could measure the diameter of? Or a pic of a flywheel? I'd love to confirm whether or not the CA=RB20 thing is true. There's probably more clutches offered for a N/A Z32 in the US than for a CA...

[SeVa-S13]

Sorry, no pics of the flywheel but the RB and Z32 clutch discs were the exact same size, whatever that may be. I'm at work right now so I can't go measure, but I'm sure you can find out online at a parts store.

Some other info :-CA18DET clutch = 200mm. CA18ET clutch = 190mm. So no, they're not compatible.

[/quote]Thats wrong cause i know for a fact that the ca18et from a rwd 200sx s12 will work cause someone on this board is using a stock s12 ca18et clutch disk and bought it from autozone or a store like it for 30 or 40 bucks.....Also i am using a 6-puck sprung dual diaphram kit for a ca18et wich works they are the same the only difference is the flywheel ours bolts to the crank with 8 bolts wich the s12 uses 6 and if i remember right 4 or 5 other people on this board are using the same exact kit i use......

I stand corrected; if I can remember which source I got that from I'll correct them as well. I've edited above to note. Thanks!

Do any of the manufacturers release plate pressures?

Specific plate pressures? I can go back through and check...

So there shouldnt be a fitment issue with a ca18et clutch. Because the one I have appearently wont fit on the flywheel. I'm sorry for being so vague but I havent really had a chance to see the car today, I just dropped off the oddessy battery and rushed off to work. The clutch is (supposed to be) an exedy 4 puck with a sprung hub. The clutch is the last thing stoping me from driving her home. I'll get more info later I'm tired and im gonna go to sleep. All responses much appreciated.

[redamnavit]

Can you get access to your four puck? If so could you measure its diameter? My stock clutch was 225mm; I'll remeasure it to be sure. I'm sure this can be figured out...

[Rookie_ca18]

Probably not until monday because this moroso event that is going on this weekend.

[Rookie_ca18]

Ok I went and saw the car today. Saw the clutch that was on it... it is a twin plate clutch and also an aftermarket flywheel and pressure plate. The flywheel seems to be a part of the clutch kit and has slots for it...so I cant use my new clutch with it, I hope to get pics of it posted this week.

Dee, if your reading this and happen to have a rwd ca18det flywheel laying around could I buy it off ya? I'll be checking out our numerous "ca stuff for sale" threads until then. Thanks.

If Dee doesn't have a spare my lightweight one should be at my door sometime next week; assuming it looks ok my stock one will be available.

Can you determine the manufacturer, or describe the clutch?

[Rookie_ca18]

Alright thanks man. Nope, it doesnt have anything written on it and no marks of any sort. When I get pics I'm sure some1 on here will know what kind it is.

[f s t caz]

from my understanding, the Nismo clutch is also a Daikin clutch, like the regular Nissan clutch. just throwing that out there...

[redamnavit]

The NISMO clutches I've seen had red pressure plates.The OS Giken clutches had gold pressure plates.The Exedy had purple pressure plates.The Cusco had blue pressure plates.

But that may not be standard across all time? No matter, we'll see when you get the pics up.
